Specification of Letters Patent.

Patented Nov. 13, 1906.

Application filed February 21, 1903. Serial No. 144,551.

To all whom. it may concern:

Be it known that I, SAMUEL G. Goss, a citizen of the United States,residing at Chicago, in the county of Cook and State of- Illinois, haveinvented certain new and useful Improvements in Molten-Metal-MeasuringApparatus, of which the following is a specification, reference beinghad to the accompanying drawings.

My invention relates to molten-metalmeasuring apparatus, and hasprincipally for its object to provide improved apparatus for supplyingmeasured charges of molten type-metal to single or multipleca'stingboxes, although it may be used for any other purpose for whichit is adapted. I accomplish this object as illustrated in theaccompanying drawings and as hereinafter described.

What I regard as new is set forth in the claims.

- In the accompanying drawings, Figure 1 is a side elevation of astereotyping apparatus embodying my improvements. Fig. 2 is a section online 2 2 of Fig. 1. Fig. 3 is a detail, partly in section, illustratingthe discharge-tube Fig. 4 is a detail, being a side elevation,illustrating one form of valve-operating mechanism. Fig. 5 is anenlarged detail, showing a modified form of valve-operating mechanism.Fig. 6 is a sectional view of the same, and Fig. 7 is a detailillustrating a further modification of the valve-operating mechanism.

Referring to the drawings, 10 indicates a furnace in which thetype-metal is reduced to a molten condition. Said furnace is providedwith a suitable chamber or bowl 1-1, in which the type-metal iscontained. Suitable heating arrangements are provided below the bowl,so. that the type-metal therein is kept in a molten condition.

12 indicates a tube which communicates with the lower portion of thebowl 1 1 and extends downward and outward, terminating outside thefurnace, as shown in Fig. 1, and having a downwardly-extending spout ornozzle 13 at its lower end.

14 indicates suitable heating appliances, preferably gas-jets, arrangedto heat that portion of the tube 12 which lies outside the furnace,except the nozzle 13, which it is not necessary to heat.

frame, which is arranged to support a multiple casting-box, so as toreceive type-metal from the nozzle 13. It will be understood that whileI have shown a multiple castingboX my improvements may be applied tosingle casting-boxes as well. In the apparatus illustrated indicates acore which is substantially cylindrical, and 29 32 the two members ofthe case, each member of the case being semicylindrical and forming witha segment of the core a complete casting-box. The core with the membersof the case is adapted to rotate about a vertical axis to bringdifferent sections thereof under the nozzle 13.

The construction of a multiple stereotyping apparatus such as thatillustrated forms no part of my present invention, but is fullydescribed and claimed in my companion application executed this day andfiled herewith, Serial No. 144,550. It will suffice for present purposesto say that the casting-box illustrated is arranged to be turned to ahorizontal position to receive the matrix and for the removal of theplate and to be turned to an upright position under the nozzle 13 toreceive its charge.

The molten type-metal is drawn from the furnace in measured quantitiesby means of butterfly-valves 33 34, mounted on shafts 35 36,respectively, as shown in Figs. 3 and 4, said shafts being operated bysegments or blocks 37 38, respectively, also carried by the shafts 3536. Said segments are engaged by a mutilated gear 39, placed betweenthem and mounted on a suitable stud or shaft 40. As illustrated in Figs.3 and 4, when the parts are in the position shown therein both valves.33 and 34 are closed and are held closed by the engagement of saidblocks with the smooth portion of the periphery of said mutilated gear.When, however, the said gear is moved in the direction indicated by thearrow in Fig. 4, the teeth 41 thereof engage the tooth 42 of the segment38 and rock said segments in the same direction, opening the valve 34.The valve 33 is, however, not affected at this time, as the smoothportionof the periphery of the gear 39 is still in contact with thesegment 37. Reverse movement of the gear 39 from the position shown inFig. 4

opens the valve 33, the teeth 43 of said gear 39 acting on the tooth 44of the segment 37 in 28 indicates a casting-boxsupporting a mannersimilar to that just described. A

lever 67 is provided for rocking the gear 39, said lever being mountedon the shaft 40, which carries the gear 39, as shown in Figs. 1 and 4.It will be observed that by the con- 'struction described the valve 33may be first opened to admit a charge of molten metal to the spacebetween said valve and the valve 34, the latter being closed. Afterclosing the valve 33 the valve 34 may be opened, permitting the chargeto pass out into the casting apparatus.

In Fig. 5 I have illustratedvalve mechanism similar to that shown inFigs. 1 to 4. Instead of providing a mutilated gear 39 in theconstruction shown in Fig. 5 I have employed a disk 45, provided witharms 46 47, carrying pins 48 49, respectively, which are adapted toenter slots in blocks 50 51, respectively, connected to butterfly-valves52 53. The blocks 50 51 are provided with concave surfaces adapted tobear against the periphery of the disk 45 when the valves are closed, bywhich construction the valves are held closed, except when opened by theaction of the disk 45. Opposite the arms 46 47 the disk 45 is providedwith concavities 54 55 to permit the rocking of the blocks 50 51 ontheir pivots 56 57, which are also the pivots of the valves 52 53, asshown in Fig. 6. The operation of this form of apparatus issubstantially the same as that shown in Figs. 1 to 4.

The modification shown in Fig. 7 is sub stantially the same as thatshown in Fig. 5, the principal difference being that in lieu ofemploying a disk 45 I employ two segments 58 59, mounted on a shaft 60and carrying arms 61 62, corresponding with the arms 46 47. The arms 6162 carry pins 63 64, which enter slots in blocks 65 66, similar to theblocks 50 51.

It will be understood that the valve mechanism shown in Figs. 5, 6, and7 is operated by a lever 67, mounted on the shaft 40, which carries themutilated gear.

IVhile I have described in detail my improvements as illustrated in theaccompanying drawings, my invention is not limited specifically to theconstruction described, but includes, generically, the invention setforth in the claims. Moreover, my improvements are not restricted intheir application to apparatus for casting stereotype-plates.

That which I claim as my invention, and desire to secure by LettersPatent, is

1. In a casting apparatus, the combina tion of a receptacle for moltenmetal, a chamber communicating therewith adapted to contain a charge ofmolten metal, a plurality of valves for effecting the delivery ofseparate charges from said chamber, and intermediate means for actuatingeither of said valves separately and meanwhile locking the other valveagainst operation.

2. In a casting apparatus, the combina- 65 tion of a receptacle adaptedto contain molten metal. a measuring-chamber communicating therewith,inlet and outlet valves controlling the admission of molten metal tosaid chamber and. its discharge therefrom, and an actuating devicehaving means for actuating said valves at different times and forlocking either of said valves when the other is actuated.

3. The combination of a chamber, a plurality of valves, and an actuatingdevice for said valves arranged to be operated to open and close saidvalves at different times and having means for locking either of saidvalves against operation when the other is operated.

4. The combination of a pair of rotary valves, a rotary disk, blocksconnected with. said valves and adapted to non-rotatably engage saiddisk when said valves are in a certain position, and means for actuatingsaid valves at different times by the rotation of said disk.
